Abstract

The embodiment of the invention provides a driver active alarm system and device based on face recognition. The method comprises the steps of obtaining the driving speed of a vehicle; judging whetherthe driving speed exceeds a first preset threshold value or not; when the driving speed exceeds a first preset threshold value, obtaining the first face information of a driver; determining a first blinking frequency and a head rotation frequency of the driver according to the first face information; judging whether the first blinking frequency and the head rotating frequency reach a second presetthreshold value or not; and when the blinking frequency and the head rotating frequency do not reach a second preset threshold value, sending the first alarm information to the driver, so that the technical problems that in the prior art, a driver driving an automobile cannot be monitored in real time, safe driving of the automobile is not facilitated, and the safety coefficient is low are solved, and the technical effects that the facial feature change of the driver is rapidly and accurately monitored in real time, timely feedback and early warning are achieved, misoperation of the driver isavoided, and the driving safety is improved are achieved.

Description

technical field [0001] The embodiment of this specification relates to the field of automobile technology, and in particular to a driver active alarm system and device based on face recognition. Background technique [0002] Face recognition technology itself is a relatively mature technology, which has been applied in many fields such as mobile phone unlocking, payment, punching machine, etc. At present, the fields where face recognition technology has been applied all have an imaging screen to let users know the area collected by the camera , can adjust the positional relationship with the camera according to the screen, and put the face into the correct collection area, so that the camera can capture enough feature points to achieve the purpose of recognition. At present, the face recognition system has been applied to the unlocking of vehicles and other fields, which can improve the safety of users' vehicles. [0003] However, the inventors of the present application ha...
